Our mission is to find the best unpublished short mystery – one that fits into legendary crime writer Margery’s definition of what makes a great story:

“The Mystery remains box-shaped, at once a prison and a refuge. Its four walls are, roughly, a Crime, a Mystery, an Enquiry and a Conclusion with an Element of Satisfaction in it.”

Entries Now Closed for 2021.

The international competition is open to all – both published and unpublished authors from all over the world – and is for short stories of up to 3,500 words. All that we ask is that the story has not been previously published anywhere, or shortlisted for this competition.

How to Write a Winning Story

We asked a former winner of the CWA/Margery Allingham Short Story competition for 6 great tips and here they are:

• Read the great short stories (not just crime fiction) and ask yourself what makes them great
• Don’t kid yourself that writing a short story is much easier than writing a novel
• Think about the effect you want the story to have on the reader
• The opening needs to arrest attention
• The end must leave the reader with a sense of satisfaction
• Between the beginning and the end – don’t waste a word
